Welcome to the 22nd Workshop website!

Workshop's mission

The International Workshop on HIV and Hepatitis Observational Databases (IWHOD) brings senior and junior HIV and hepatitis observational database researchers together to advance the methodology and analysis of observational data. No other workshop or conference devotes attention to the methodology of setting up and analyzing observational data, despite their importance in providing critical information on population outcome in real world settings outside the controlled setting of randomized trials. We are once again aiming to include attendees representing cohort studies from all regions. As in the past, we encourage discussion of work in progress, so all data presented will not be publicised outside of the Workshop.

Financial assistance: We continue to strongly encourage abstract submissions from resource-constrained settings. Recognising that the additional expenses may deter some from attending the meeting, we will try to offer financial assistance for delegates from resource-constrained settings, particularly those with student status, whose abstracts have been accepted. Please contact the Secretariat for details (secretariat@IWHOD.org). When submitting your abstract you will be asked whether you qualify for financial assistance.

Young Investigator Award:Two Young Investigator Awards for early career researchers will be given at the end of the workshop, one for best oral and one for best poster. When submitting your abstract you will be asked whether you qualify for this Award.
